The Ultimate Guide to HPLC/UHPLC Reversed-Phase Selectivity

This application note highlights the benefits of the LipiFiltr® cartridge for multi-class, multi-residue pesticide analysis in complex, high-fat samples.

Using HALO®Elevate C18 and a high pH mobile phase obtains a great separation of drugs of abuse and metabolites without the use of a specialized stationary phase.

Over the course of 5000 injections, the HALO®Elevate C18 1.5 mm ID column demonstrates stability and robustness in the stationary phase and the column hardware, with no significant changes to the retention time, peak shape, and back pressure.

A mix of four antidepressants is separated using the HALO®PCS (positive charged surface) C18 column demonstating the improved tailing factor and efficiency when compared to a traditional (uncharged) C18 stationary phase.
